sanic: Solving Ax = b Nimbly in C++

Direct and iterative methods for solving linear systems and computing eigenvalue and singular value decompositions using the Eigen C++ library in R. Supports dense and sparse linear systems with Cholesky, LU, QR, conjugate gradient, stabilized biconjugate gradient, and least-squares conjugate gradient methods. Provides reusable factorizations for repeated solves.
